Whichever one is closer, at some points i've basically lived a few years of potatoes (and some other foods combined with potatoes), later on rice and in between lived of pasta. All just whichever one i have at home, and whichever i feel more like eating.

but they are three options that doesn't work for most of the world. North and south america, europe and parts of asia eat bread. Many parts of africa don't have any of those 3 staples.

Out of the foods the OP considers staples, which do you like best? Look at the question that way, rather than getting upset that it doesn't contain your preference, or everyone's preference. It's his thread, he can choose the poll options.

Well his actual question at the end of his post was "So what is your preffered carbohydrate source?"
